-----------------------------------

Can you provide any further details here, broker logs?  Unit tests?  Broker config?  Context
on when this happens/happened?  Anything???

>                 URL: https://issues.apache.org/jira/browse/AMQ-4214
>             Project: ActiveMQ
>          Issue Type: Bug
>          Components: Message Store
>    Affects Versions: 5.7.0
>         Environment: Red Hat Enterprise Linux Server release 5.7 (Tikanga)
> System had been up for 15 days.
> The "Messages Enqueued" in the Topics tab for our topic was negative (~-63000)
> The Subscriber tab showed about 14,000 in the Pending Queue Size and was not decreasing.
 Messages Enqueued/Dequeued were incrementing and messages were being delivered (this is a
real-time queue).
> So I deleted the Q.  Then we could not recreate the Q and got the message below.
> Other topics in the system appeared to be fine.
> I had been doing a fair amount of testing on client error recover dropping port connections
and IP connections using the firewall so was aborting connections frequently (though not doing
a lot at once).
> A number of times (due to a bug) tried to make a duplication connection to the Q.  I'm
not sure exactly when the topic went haywire.
> We are running over a WAN with about 30ms latency.
> Can't think of anything else we were doing different than anybody else.
> Here's our connection
>             ActiveMQConnectionFactory tcf =new ActiveMQConnectionFactory(cs);
>             conn = tcf.createTopicConnection();
>             String iName = prop.getTopicSubscriberName();
>             conn.setClientID(iName);
>             session = conn.createTopicSession(false,TopicSession.AUTO_ACKNOWLEDGE);
>             topic = session.createTopic(prop.getBigDataRepositoryTopicName());
>             conn.start();
>             String sName = iName;
>             subscriber = session.createDurableSubscriber(topic, sName);
